...make Caves, Swamps and Snow look more like they did in Morrowind?

I loved the "organic" caves in Morrowind. Oblivion's are so dry and sterile, although Ampol's new one are a step in the right direction with their "wet look".

Parts of the Blackwood Forest is supposed to be swamp, but doesn't look like swamps. Swamps are supposed to be wet places, not dry.

The snowy areas in Jerall Mountains and around Bruma are more like a thin layer of frost on the ground, rather than real snow. http://tesnexus.com/downloads/file.php?id=26625 has some excellent snowy ground and tree textures, but when it's snowing it's not nearly the same as when it snowed in Morrowind/Solstheim. On Solstheim the snow drift was real thick and it felt real. Oblivion's snow weather feels more like a cheap Hollywood movie. I haven't installed the latest version of All Natural yet, but maybe real snowy weather is a job for All Natural?

I guess there is just too little room for making improvements in these areas, since it hasn't alrady been done?
